GYNECOLOGICAL STIRRUP.

SPECIFICATION forming part of Letters Patent No. 357,694, dated February15, 1887. Application filed March 25,1886. Serial No. 196,604. (Nmodel.)

To all whom it may concern:

Be it known that I, CARL H. VON KLEIN, of Dayton, Montgomery'county,Ohio, have invented certain new and useful Improvements in GynecologicalStirrups, of which the following is a specification.

Th'isinvention has referenceto a contrivance for use by thegynecological practitioner in connection with the gynecologicalmanipulations and operations.

The invention relates to the construction of a foot-rest adapted forready attachment to the rail of a bedstead or to the edge of a table,

- whereby the patients feet may be supported in the proper position.

The invention will be readily understood from the following description,taken in connection with the accompanying drawings, in which- Figure 1is a perspective view illustrating one of a pair of my devices, shown asattached to the rail of a bed or similar article presenting its edgevertically; Fig. 2, a side elevation of the device shown as applied tothe edge of a table or similar article presenting its edge horizontally;Fig. 3, a longitudinal section through the movable clamp-jaws, showingthe .arrangement of the tighteningcam; Fig. 4, a

transverse section of the same, and Fig. 5 a perspective view of thecoupling ends of the stirrup-bar and clamp-shank.

In the drawings, A indicates a portion of a table or similar articlewhose edge presents horizontally; B, a portion of the rail of anordinary bedstead, the edge of such rail presenting itself vertically;O, a jawed clamp adapted to engage firmly'with the furniture part towhich it may be attached; D, a stirrup-bar projecting outwardly from theclamp; E, the clamp-shank reaching from the clamp outward intoengagement with either end of the stirrup-bar; F, the joint of unionbetween the clamp-shank and the stirrup-bar, the same being formed byrabbet-laps, as seen in Fig. 5,

whereby the joint will be secured whether the stirrup-bar forms a directextension of the clamp-shank or extends at right angles thereto; G, athumb-screw serving to hold the stirrupbar to the clamp-shank inwhichever of its two positions it may be placed; H, a stirrup orfoot-piece formed upon the outer end of the stirrupbar; J, the movablejaw of the clamp, the same being fitted to slide upon the clampshank, soas to adapt itself approximately to different thicknesses of attachingparts; K, a thumb cam pivoted in the movable jaw; L, a pad disposedwithin the movable jaw and adapted to engage its face against the pieceto which the device is clamped; M, a connecting block pivoted to the padand reaching outward through a mortise in the movable jaw, andpresenting an outer face against the periphery of the cam; N, a ribformed upon the side of the clamp-shank and engaged by a side grooveinthe mortise ofthe movablejaw where 6 thesame engages the clamp shank; O,facings of chamoisskin or other soft material applied to the clamp-jawsto prevent the marring-of furniture, and P recesses in clamp jaws toclear edge-moldings on furniture.

In using these devices two of them are attached to the bedstead ortable, as the case may be, at-such distance apart as will place thepatient s feet in proper position. In case the devices are attached tothe bed-rail or other article presenting its edge vertically, thestirrup-bar will be so attached to the clamp as to project at rightangles to the opening between the clamp-jaws, as shown in Fig. 1, whileif the stirrups are to be attached to a table-top or other articlepresenting its edge horizontally the stirrup-bar will be so attached tothe clamp asto project outwardly parallel to the opening in thestirrup-clamp, as clearly shown in Fig. 2. The union-joint F and screw Gpermit the ready attachment of the stirrupbar in either of thesepositions, and also permits of the parts being disjointed for thepurpose of'more compact storing when not in use. The shoulders of therabbets of the joint form 0 positive stops or thrust-bearings for theparts in either position of the bar, thus preventing accidents andrelieving the screw of all but shearing strains. The movable jaw Jslides very loosely upon the-clamp-shank, so that it 9 5 may be slidalong thereon and be adjusted approximately to the thickness of thearticle with which the clamp is to engage, and when the strain isbrought upon the movable jaw of the clamp it will cant somewhat upon therco clamp-shank and take a frictional bite upon the rib N withsufficient force to prevent the further movement of the movable jaw awayfrom the fixed jaw. The oscillation of the thumb-cam, serving to pressthe pad firmly against the face of the article to be clamped, and thepad being pivoted to the connectingblock, is at liberty to adjust itselfto inequalities of surface. The connecting-block loosely engages theaxis of the thumb-cam through the medium of a slot which prevents theconnecting-block becoming separated from the other parts Withoutpreventing the proper inward and outward movement of the block.

I claim as my invention" 1. A gynecological apparatus consisting of twofoot-pieces, each provided with an openjawed clamp, combinedsubstantially as set forth, and adapted for engagement in adjustablerelation to each other with furniture, for the purpose specified.

2. A gynecological apparatus consisting of two stirrup-bars providedwith stirrups or foot-pieces and two open-jawed clamps connected to saidstirrup-bars by joints provided with stops or thrust-bearings adapted tosupport said stirrup-bars rigidly in a position either parallel with orat right angles to the jaw-openings of said clamps, combinedsubstantially as set forth, and adapted for en gage ment in adjustablerelation to each other with furniture, for the purpose specified.

3. In a gynecological stirrup, the combination of an open-jawed clampadapted for attachment to the edge of furniture, a clampshank projectingtherefrom, a stirrup-barprovided with a foot-piece and engaging saidclamp shank by rabbetlaps forming stops or thrust-bearings, and athumb'screw uniting the stirrup-bar to the clamp-shank, substantially asand for the purpose set forth.

4:. In a gynecological stirrup, the combination, with a clamp, astirrup-bar, and a footpieee, of a thumb'cam pivoted to one jaw of theclamp, a connecting-block, and apad pivoted to the connecting-block,substantially as and for the purpose set forth.

5. In a gynecological stirrup, the combination, with a clamp, astirrupbar, and a footpiece,of the rib N and the slidingjaw fitted withtightening mechanism and adapted for canting engagement with said rib,substantially as and for the purpose set forth.
